2. Add the JNEG execute state to the CASE statement in the model. JNEG is Jump if AC <

0. If A >= 0 the next sequential instruction is executed. In most cases, a new instruction will just require a new execute state in the decode CASE statement. Use the opcode value of 04 for JNEG. Test the new instruction with the following test program that implements the operation, IF A>= 0 THEN B = C
